Better and faster velocity pulsatility assessment in cerebral white matter perforating arteries with 7T quantitative flow MRI through improved slice profile, acquisition scheme, and postprocessing
PURPOSE: A previously published cardiac‐gated 2D Qflow protocol at 7 T in cerebral perforating arteries was optimized to reduce velocity underestimation and improve temporal resolution. METHODS: First, the signal‐to‐noise ratio (SNR) gain of the velocity measurement (SNR(v)) was tested for two signa...
